The present invention relates to a sectional floor-covering capable of adjusting level, which includes a height adjusting block; a supporter coupled to the upper surface of the height adjusting block; slip floorings coupled to the upper surface of the supporter; and horizon adjusting devices mounted to the height adjusting block. The height adjusting blocks and supporters are assembled and installed at a desired position, and slip floorings are mounted and fixed on the assembled height adjusting blocks and supporters so as to install the floor to a wanted height.

TECHNICAL FIELD

The present invention relates to a sectional floor-covering mounted on a balcony in a building such as an apartment. More particularly, the present invention relates to a sectional floor-covering capable of adjusting level, which includes a height adjusting block; a supporter coupled to the upper surface of the height adjusting block; slip floorings coupled to the upper surface of the supporter; and horizon adjusting devices mounted to the height adjusting block.

BACKGROUND ART

In general, in most of apartments, a balcony is mounted on the outer part of a living room, and the floor surface of the living room is constructed higher than the floor surface of the balcony, and thereby, the border between the living room and the balcony has a stepped part of a predetermined height.

So, in case of that the existing balcony is remodeled into a part of the living room to use the living room wider, construction workers pour concrete on the floor surface of the balcony and level up the height of the balcony to that of the living room. However, such construction for leveling up the floor height of the balcony by pouring concrete on the floor surface of the balcony may cause a large-scale accident, such as its own collapse, as exceeding support intensity in an aspect of structural mechanics of the balcony without regard to whether or not it is admitted by the construction laws. In addition, when the balcony is remodeled, it hinders neighbors' living as there occurs noise, and it requires excessive construction costs.

As described above, the floor height of the balcony can be leveled by pouring concrete. Furthermore, as another method to level the floor height of the balcony, as shown in FIG. 1, balks 6 are fixed on the floor with nails to be adjusted in level, and then, strip flooring boards 1 are fixed on the balks 6 with nails or adhesives. However, the flooring construction generates lots of noise and is expensive. Moreover, the conventional flooring construction has another disadvantage in that it is difficult for non-skilled persons to construct the floor.

To solve the above problems and to construct a balcony of the same level as a living room by a simple construction method, sectional floor coverings of various kinds have been used, but most of them cannot be adjusted in level. So, if the surface of the floor installed in the balcony and the surface of the floor installed in the living room are not leveled, spacers are mounted under the sectional floor coverings, so that the floor mounted in the balcony is leveled with the floor of the living room.

Furthermore, there is another sectional floor covering capable of adjusting level without mounting of spacers. However, in the sectional floor covering capable of adjusting level, a sectional supporter is mounted on the upper portion of a height adjusting block, a strip flooring is fixed at the upper portion of the sectional supporter, and a height adjusting unit is mounted at the lower portion of the height adjusting block. So, to adjust height, the sectional floor covering must be turned over, and therefore, it is inconvenient to adjust height, and it takes lots of time to adjust height.

BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings.

As shown in FIGS. 2 and 3, a height adjusting block 10 includes connecting tongues 11 formed on the upper surface of a height adjusting block 10, vertical holes 12 perforating the upper surface and the lower surface of the height adjusting block 10, and built-in nuts 13 respectively embedded and fixed in the vertical holes 12.

The shape of the connecting tongues 11 is not restricted to the shape shown in FIG. 2, and one of various shapes, such as a circle, an oval and others, can be selected. Also, the shape of the section of the vertical hole 12 is not restricted to the shape shown in FIG. 2 or 3, and one of various shapes, such as a circle, a hexagon and others, can be selected if the built-in nut is embedded and fixed therein and spaces for moving screw bars of horizon adjusting devices 40 vertically through the vertical holes 12 are secured.

The connecting tongues 11 of the height adjusting block 10 are coupled with connecting holes 21 of a supporter 20 shown in FIG. 4, and the horizon adjusting devices 40 are mounted in the vertical holes 12 respectively, in which the built-in nuts 13 are embedded, as shown in FIG. 11. Meanwhile, as shown in FIG. 2 or 6, semicircular drain holes 14 are formed in the lower surface of the height adjusting block 10 to allow a smooth water flow along a water curving slant surface of the floor of a balcony. Moreover, as shown in FIG. 3, connecting grooves 15, which will be coupled with the connecting tongues 11, are formed at the lower surface of the height adjusting block 10 in correspondence with the shape of the connecting tongues 11, so that a number of the height adjusting blocks 10 can be piled up by coupling the connecting tongues 11 with the connecting grooves 15.

As shown in FIG. 4, the supporter 20 includes: connecting holes 21 formed in the lower surface thereof, which will be coupled with the connecting tongues 11 corresponding to the shape of the connecting tongues 11 of the height adjusting block 10; vertical working holes 22 formed in positions, where they correspond with the vertical holes 12 of the height adjusting block 10, to perforate the upper and lower surfaces of the supporter 20 under a condition in which the height adjusting block 10 and the supporter 20 are coupled with each other by the connecting tongues 11 and the connecting holes 21; connection protrusions 23 extending from a side of the upper surface of the supporter 20 and protruding vertically; connection receiving parts 24 extending from the other side of the upper surface of the supporter 20 and corresponding to the shape of the connection protrusions 23; and slip flooring connection pins 25 protruding from the upper surface of the supporter 20 vertically. The connection protrusions 23 are coupled to the connection receiving parts 24 formed on another supporter 20, which is mounted adjacent to the present supporter 20, so that a number of supporters 20 can be connected vertically and horizontally to expand the floor covering.

As shown in FIG. 4, the connecting holes 21 formed in the supporter 20 can be formed to perforate the upper and lower surfaces of the supporter 20, are not restricted to the shape shown in FIG. 4, and can have any shape if the connection protrusions 23 and the connection receiving parts 24 are connected with each other to continuously connect a number of the supporters 20 vertically and horizontally. The shape of the slip flooring connection pins 25 is not restricted to the shape shown in FIG. 4, and can be selected from various shapes capable of fixing a slip flooring 30 by being coupled with coupling grooves 31 respectively formed in the lower surfaces of the slip floorings 30.

The slip coupling groove 31 formed in the lower surface of the slip flooring 30 has the same shape as the slip flooring connection pin 25, so that the slip floorings 30 can be fixed to the supporter 20 by coupling the slip flooring connection pins 25 with the coupling grooves 31 thereof.

As shown in FIG. 11, the horizon adjusting device 40 includes a screw bar 41 having a screw thread, a head part 42 formed on an end portion of a side of the screw bar 41, and “+” or “−” shaped driver hole 43 formed in the front end portion of the other side end of the screw bar 41. The screw bar 41 is inserted into the lower surface of the height adjusting block 10 coupled to the built-in nut 13.

Therefore, when the horizon adjusting devices 40 are coupled with the built-in nuts 13, the screw bars 41 can be moved vertically while rotating through the vertical working holes 22 of the supporter 20 and the vertical holes 12 of the height adjusting block 10, and it can be checked if a worker looks down the driver hole 43, which is formed at the front end of the screw bar 41, at the upper surface of the supporter 20, as shown in FIGS. 9 and 10. The reason is that positions of the vertical holes 12 of the height adjusting block 10 and those of the vertical working holes 22 of the supporter 20 are corresponded with each other when the height adjusting block 10 is coupled with the supporter 20, and that the screw bar 41 is coupled with the built-in nut 13 embedded in the vertical hole 12 of the height adjusting block 10. Therefore, the screw bar 41 can be moved vertically by rotating the screw bar 41 using a simple tool, such as a driver, through the vertical working hole 22 and the vertical hole 12 from the upper surface of the supporter 20. As described above, the present invention can adjust level of the floor coverings conveniently by rotating the screw bar 41 of the horizon adjusting device 40 using the simple tool, such as the driver, from the upper surface of the supporter 20 under a condition that the height adjusting block 10 and the supporter 20 are coupled with each other and the combination of the height adjusting block 10 and supporter 20 is spread on the balcony.

Furthermore, as shown in FIG. 11, the screw bar 41 of the horizon adjusting device 40 further includes a locking nut 44 without regard to the built-in nuts 13 embedded in the vertical hole 12 of the height adjusting block 10. The locking nut 44 can prevent rotation of the screw bar 41 when the adjustment of level is finished, thereby providing floor stability of the floor coverings. In other words, when the screw bar 41 is fixed and the locking nut 44 is rotated and tightened, the screw bar 41 of the horizon adjusting device 40 is tightly fixed to the height adjusting block 10 to always maintain a uniform height. In addition, as shown in FIG. 11, the head part 42 of the horizon adjusting device 40 is packed with a rubber cover 45 to prevent slip of a tile floor surface of the balcony or a bath room.

FIG. 12 shows a state in which the slip flooring 30 is assembled to the sectional floor covering capable of adjusting level according to the present invention. In the drawing, the connecting tongues 11 of the height adjusting block 10 are coupled with the connecting holes 21 of the supporter 20, and the coupling grooves 31 of the slip floorings 30 are coupled and fixed to the slip flooring connection pins 25.

FIG. 13 is a brief view of a detail embodiment of the present invention, in which the supporter 20 is assembled onto the height adjusting bock 10 and the slip flooring 30 is attached to the upper surface of the supporter 20. In the drawing, the horizon adjusting device 40 is not shown, but the head part 42 of the horizon adjusting device 40 is mounted on the lower surface of the height adjusting block 10, and at this time, the head part 42 is directed toward the ground.
